07_18_13Diminished indoor air quality is more likely to become a problem for you the more time you spend indoors this summer. Particulates in your home’s air could aggravate allergies or respiratory conditions. Excess humidity could damage your belongings or even your home’s basic structure. Disease-causing micro-organisms could invade your body and make you miserable. Here are three effective add-ons for your HVAC system that can improve indoor air quality.

1. Dehumidification. Humidity inside your home normally increases during the summer. Along with the weather-related increases, normal sources of indoor moisture such as cooking, showering and clothes washing will keep adding humidity to your indoor air. A tightly sealed home, while energy efficient, will be more likely to hold excess moisture.

Whole-house dehumidifiers substantially reduce moisture and improve indoor air quality. They are installed within the airflow of your forced-air cooling system. As the air that cools your home circulates, it also passes through the dehumidifier, where moisture is removed before the air continues on into your home.

Indoor relative humidity should be somewhere between 30 to 50 percent. Controlling your indoor humidity will decrease the physical effects often felt in humid environments, such as tiredness and aggravation of respiratory conditions. It will prevent the growth of mold, insects, mildew, bacteria and other pests that thrive on moisture. It also will reduce the possibility of moisture damage to books, papers, wood, furniture and electronics.

2. Filtration. Your air conditioner provides basic air cleaning through its air filters. That is why indoor air quality requires regular changes of the filters in your HVAC system. If you need or want a greater level of air filtration and particle removal, an air purification or filtration system will help. These devices are also placed within the airflow of your central air conditioning system. The higher-quality filters in these units capture and hold particulates such as dust, pollen, mold, animal dander, fibers and other solid contaminants.

Some filtration systems are available with activated charcoal filters that can remove fumes and odors in addition to particulates.

3. Ultraviolet (UV) light systems. UV light systems are a powerful weapon against biological contaminants and disease-causing micro-organisms. These units are designed to treat the air coming from your HVAC system with ultraviolet light. As UV light shines on micro-organisms, it either kills them outright or damages their DNA, which makes them unable to reproduce. Organisms that cannot reproduce cannot multiply and spread, preventing them from causing disease.
